Abstract In the 21st century, human health, water safety, and environmental
pollution are the main crucial issues all over the world. Many hazardous organic
and inorganic pollutants present in the groundwater, surface water systems create
havoc in the environment as well as drinking water. Waterborne diseases are
dangerous for human health and other animals. Thus development of the simple and
user friendly methods of for the easy detection of the water pollutants are necessary
for healthy society. Graphene is one of the most promising and wonderful carbon
hybrid materials as it possesses many outstanding properties like honeycomb
structure, high surface area, unique physical, mechanical and chemical properties,
etc. The nanoparticles such as Au, Ag, and Cu possess shape, and size-dependent
surface plasmon resonance (SPR) absorption bands thus can be used to construct
plasmonic-based sensors. Recently 2D graphene and its composites are widely used
as a support to these metal nanoparticles to improve sensitivity and selectivity
towards the analytes. These nanocomposites are widely used to detect hazardous
environmental pollutants by different techniques like colorimetric, fluorometry, and
electrochemical sensing. There are several reports on designing graphene quantum
dots/metal nanoparticle based system for sensing application for water pollutants
like organic pollutants, gold, silver, mercury, iron, etc. These techniques are very
simple and do not require expensive facilities, highly skilled manpower, and easy to
operate. This chapter is mostly focussed on the synthesis of monometallic and
bimetallic plasmonic nanoparticles decorated graphene/graphene quantum dots
system for the detection of water pollutants. The recent development of the
detection of water pollutants by colorimetric, fluorometric, and electrochemical
